Vazios urbanos e a dinâmica imobiliária na produção do espaço em Natal

In Brazil, the discussion about the urban voids appear related to the capitalist urban expansion process, when the urban growth act the cities were expanding toward the periphery, leaving in the interstices vacant land, kept out of the market waiting for the real estate valuation. In Natal, the formation of voids was triggered by the process of fragmentation of space promoted mainly by the urban sprawl with the emergence of new neighborhoods, lots of openings, housing developments and the emergence of new lines of commercial centrality. In this sense, this study aims to understand the role played by urban voids in the real estate dynamics and the production process of the Natal city space. For this, it was adressed the concept building on the conception of different authors and were characterized four types of gaps that best explained the phenomenon in the context of the work proposal addressed, such as idle, empty expectant, empty-brownfield areas and institutional areas. For each of these events were considered an example in the general context of the city through semi-structured interviews with technicians, managers and public officials in promoting the city and /or related to management of urban voids.

A dinâmica geográfica da construção de um território para moradias sociais: estudo testemunhal do empreendimento Vitória Brasil em Uberlândia (MG)

This work describes and analyzes the situation planned with the current, according to the housing development project style of social interest (Gleba 9), named Victory Brazil at Shopping Park II neighborhood, located in the southern sector of Uberlândia (MG), built with Program resources Minha Casa, Minha Vida (PMCMV). The specific objectives are: to present the housing policy of social interest directed to the Minha Casa, Minha Vida in the city of Uberlândia, from its history to its current information; trace the environmental characterization of the housing Vitoria Brazil through the development of thematic maps; identify the impacts generated by the housing projects of social interest; and show through interviews with 25 residents of Vitoria Brazil, the structural problems of the houses. Therefore, the research became quali-quantitative with descriptive approach and use of semi- structured interviews to collect data. In addition, the iconographic sources, ie photographs of the problems raised by the residents of the whole Victory Brazil and maps of the study area, enlarged the qualitative and dialogic nature of this study, as there is opportunity to contextualize specific way what was reported the residents interviewed. We understand that the city is intrinsically related to the design of agglomeration, characterized by the production of the possessor market capitalism a public administration system that is guided by the ideals of consumption and utilization of space, and its inhabitants are high class with the construction of equipment and adequate social services. One of the important biases to solving the problems of urbanization is by the intervention of the government through public policies through the master plan so that would allow prospects to enable the population of low-income housing in locations that offer housing and decent urbanization conditions.

Ideologia da casa própria... sem casa própria: o Programa de Arrendamento Residencial na cidade de João Pessoa-PB

Brazilian Housing policy has always promoted homeownership. In 1999, a new form of housing promotion was set up in the country with the PAR (Programa de Arrendamento Residencial, or residential rental programme). This is a sort of leasing, in which a right to buy is granted at the end of contract. Again, with this, the final objective is homeownership. This dissertation aims at further understanding the role of PAR in the wake of the country s housing policies of the post-BNH period, analysing the case of João Pessoa, capital city of Paraíba state. By focusing in the city, it has been possible to analyse also the impact of the programme in the dynamics of the city s urban development. Accordingly, the analysis of PAR seeks to understand the programme s operational aspects as well as its location, urban and architectural aspects. The operational aspects refer to how the programme is operated, considering the differences to the other housing programmes in the country. The urban and architectural aspects refer to location, typology and construction characteristics of housing estates produced under the scheme. This study gives a general view of the country s recent housing policy and programmes and the specific characteristics of PAR, observing also its impacts in the city development

O terciário (re) desenhando a periferia: a região administrativa norte de Natal/RN, na última década do século XX, servicializada na Av. Dr. João Medeiros Filho

The tertiary sector has been (re)defining and (re)qualifying, in an impacting way, the urban spaces in the cities, introducing new elements for the discussion of the relationship center/periphery. In Natal, as an inducing economic activity of its development, it conforms to the new needs of the capital, expanding, being materialized through several processes and spatial forms. We aim at analyzing one of those processes, which has taken its Northern Administrative Area to (re)define the design of its urban space, through the actions developed by the agents involved with the spatialization of the tertiary activities, at the same time as it redimensions its role as a periphery of Natal, contributing to the study of the recent and growing transformations of the Brazilian capitals. The studied district corresponds to 39.4% of the municipal area and, until recently, was composed by precarious reproduction spaces, unprovided of relevant economical activities. After the boom of the development of extensive housing complexes by SFH/BNH, the area, gradually stopped being a dependent area, and it imposed itself as an economically participant region, with the increase of the trade and services sectors, as well as a favorable place for the appearance of new activities. Its reflexes are noticeable in the achieved spatial configuration. As the main road to induct changes, Dr. João Medeiros Filho Avenue presents these new tendencies in the production of the intraurban space, concentrating the largest goods and services equipments of the area, through investments of the private and public sectors, which guarantee the capital allocation for the construction of a new centrality

Por uma moradia termicamente confortável: proposta de habitação de interesse social com ênfase no conforto térmico

This research covers the topic of social housing and its relation to thermal comfort, so applied to an architectural and urban intervention in land situated in central urban area of Macaíba/RN, Brazil. Reflecting on the role of design and use of alternative building materials in the search for better performance is one of its main goals. The hypothesis is that by changing design parameters and choice of materials, it is possible to achieve better thermal performance results. Thus, we performed computer simulations of thermal performance and natural ventilation using computational fluid dynamics or CFD (Computational Fluid Dynamics). The presentation of the thermal simulation followed the methodology proposed in the dissertation Negreiros (2010), which aims to find the percentage of the amount of hours of comfort obtained throughout the year, while data analysis was made of natural ventilation from images generated by the images extracted from the CFD. From model building designed, was fitted an analytical framework that results in a comparison between three different proposals for dwellings housing model, which is evaluated the question of the thermal performance of buildings, and also deals with the spatial variables design, construction materials and costs. It is concluded that the final report confirmed the general hypotheses set at the start of the study, it was possible to quantify the results and identify the importance of design and construction materials are equivalent, and that, if combined, lead to gains in thermal performance potential.

Interesses da habitação social : políticas e processos no Rio Grande do Norte

En 2003, le gouvernement brésilien (gestion Lula) a initié une nouvelle phase dans son histoire de l habitation, en intensifiant les constructions de logements sociaux au Brésil. Un tel accroissement a eut des répercussions tant en ville comme à la campagne, et fût marqué dans le Rio Grande do Norte, par la production a grande échelle d ensembles d habitations, dans les programmes de Gouvernement. Afin de viabiliser ces transformations, des instruments politiques, financiers et de gestion ont étés articulés conjointement, utilisant la répétition d une typologie d édification, comme modèle, accompagnée de la reproduction d une morphologie dans les constructions de logements sociaux. Afin de comprendre ce processus nous introduisons une recherche urbanistique et socio-économique du problème du logement social au Brésil, en cherchant à mettre en relation les aspects techniques avec les questions historique, professionnelles et culturelles, éléments complémentaires. Notre analyse cherche a identifier comment les politiques de gestion et financement officielles (administrées dans sa grande majorité par la Caisse Économique Fédérale -CEF-), influencent le processus de conception de projets, en provoquant les répétitions de type/morphologiques, déjà citées. Basée sur l observation directe au cour de deux expériences différenciées pour du logement social en milieu rural, au Rio Grande do Norte, nous montrerons aussi certaines limitations et possibilités des acteurs sociaux, face aux agents et politiques officielles pour le logement social au Brésil, proposant des solutions alternatives standardisées qui caractérisent le résultat des projets financées et gérés par la CEF.

INDUSTRIALIZAÇÃO, DINÂMICA TERRITORIAL E IMPLICAÇÕES SOCIOAMBIENTAIS EM MATO GROSSO DO SUL/BR

O trabalho se refere a um estudo sobre a industrialização, a dinâmica territorial e as implicações socioambientais em Três Lagoas/MS. O Parque Industrial decorre do processo de (des)concentração/(re)concentração industrial, no Brasil. Há intensa dinâmica territorial, que se dá a partir do processo industrial, que se circunscreve em três Distritos Industriais. Analisaram-se a estrutura e a dinâmica industrial, bem como os conflitos estabelecidos entre as forças produtivas. Também se avaliaram as alterações decorrentes da incorporação de tecnologia, produtividade e os reflexos no uso e ocupação das terras no campo. Ainda averiguou-se se há riscos de contaminação pelas indústrias, seja pela contaminação das águas subterrâneas e do solo, seja pela emissão de gases na atmosfera, os quais foram avaliados com vista à elaboração de um plano de redução dos riscos de eventos perigosos e contaminação ambiental. No Distrito Industrial I, há 22 empresas, sendo 11 ligadas a construção civil, de baixa periculosidade, e, perigosas destacam-se 3 metalúrgicas, uma química, uma de plástico e uma carvoaria. No Distrito Industrial II, concentram-se 27 empresas, destas apenas 3, a de alimentos, bebidas e de construção civil não são perigosas. Destacando-se dentre a perigosas, 8 indústrias têxteis, 6 metalúrgicas e 6 petroquímicas. O Distrito Industrial III situa-se fora do núcleo urbano, e se destina às megaindústrias: fábricas de papel e celulose, - consórcio Fibria/Internacional Paper - e uma de fertilizantes da Petrobras. As indústrias do Distrito Industrial II contam com aparato tecnológico mais avançado, isto é, coadunam as novas tecnologias do atual período técnico-científico e os incentivos fiscais – doação de terreno, isenções de impostos - com o aparato de objetos espaciais que o município oferece - vias intermodais, energia elétrica, e, a possibilidade da exploração da força de trabalho com baixos salários. Esses empreendimentos promoveram nova dinâmica territorial, criando novos sentidos e funções, impondo novos valores e cultura, inclusive os estilos de moradia, pois a expansão da periferia da cidade agora, não dá lugar somente aos conjuntos habitacionais populares, mas também aos luxuosos condomínios horizontais fechados; além do aumento da opção de moradias em condomínios horizontais. A paisagem urbana se metamorfoseia, pois a territorialização do capital industrial delineia novas territorialidades, a cidade ganha ares de cidade grande.

VISITA A CORTIÇOS EM SÃO PAULO UMA EXPERIÊNCIA DIDÁTICA

Este trabalho é fruto da disciplina AUP 5707 - ÁREAS RESIDENCIAIS - LOCALIZAÇÃO E PLANEJAMENTO: favelas e cortiços, ministrada no segundo semestre de 2008[1] como atividade da linha de pesquisa Habitat do curso de Pós- Graduação da Faculdade de Arquitetura e Urbanismo da Universidade de São Paulo. A metodologia do curso envolveu seminários associados tanto aos textos sugeridos pelos professores como à avaliação dos trabalhos de campo. Tais  visitas  foram   direcionadas para o caso dos cortiços, das favelas e dos conjuntos habitacionais de São Paulo. Para a elaboração deste painel, selecionamos o trabalho de campo que teve como foco os cortiços de São Paulo localizados na rua João Teodoro, bairro do Peri.  Os aspectos captados pelas fotografias e entrevistas revelam o predomínio de uma situação de precariedade das condições sociais e de habitabilidade dos cortiços, contrastando em parte com as condições de infraestrutura de seu entorno, considerando a sua localização próxima ao centro da cidade.

Pobreza multidimensional na região nordeste: uma aplicação da Teoria dos Conjuntos Fuzzy (em 2010)

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior

SIG aplicado na identificação de áreas potenciais aos investimentos habitacionais Estudo de caso: porção oeste do Município do Rio de Janeiro.

A expansão industrial e o desenvolvimento territorial na porção oeste do Município do Rio de Janeiro trazem inúmeras modificações no cenário socioeconômico da região e adjacências. O destaque de investimentos na indústria de transformação é a implantação da Companhia Siderúrgica do Atlântico (CSA), que se mostra como o maior empreendimento privado em realização no país. Investimentos públicos e privados no setor de infraestrutura estão previstos, considerando as características naturais e a localização geográfica privilegiada da região. A influência do porto de Itaguaí e a construção do Arco Metropolitano configuram um corredor de desenvolvimento com reflexos positivos logísticos e socioeconômicos, não só para o estado do Rio de Janeiro, mas também para outros estados brasileiros. Os impactos da reordenação do espaço urbano, com a possibilidade de incremento populacional nas proximidades do novo eixo rodoviário e industrial, tende a gerar um aumento da demanda por serviços no setor terciário. Dessa forma, o planejamento territorial se faz obrigatório, apoiado por geotecnologias. O objetivo da pesquisa foi atender às necessidades do setor habitacional, analisando fatores relevantes e condições favoráveis à implantação de novas construções habitacionais. Baseando-se em dados provenientes do censo do IBGE de 2010 e do Instituto de Urbanismo Pereira Passos (IPP), a Tecnologia da Informação integrada com os dados de mapas digitais e imagens de satélite de alta resolução (World View-2), permitiram uma análise geral do contexto do crescimento regional. Além da análise das variáveis existentes nos dados socioeconômicos, outras variáveis de pesquisa foram empregadas em ambiente SIG, tais como: segurança, proximidades de logradouros principais, existências de escolas e hospitais municipais e estaduais, distância dos centros industriais e de shopping. Após as análises multicriteriais de dados socioeconômicos e bases cartográficas, relatórios na forma de mapas foram emitidos, com a finalidade de orientar o poder público e as construtoras nas tomadas de decisões.
